MACHINE FRAME.

Application filed J'une 27, 1925, Serial No. 40,121, and in Sweden June 6, 1924.

This invention relates to machines general type of a planer.

Heretofore the machine frames were provided with projecting parts, recesses or the like, which were necessary for the mounting of the operative machine parts. When such projecting parts or recesseswere present, they required special working such as boring, planing and so forth, and this working had to be carried out in different ways on difierent occasions according to the greater or smaller width of the machines, particularly as the size of the shafts varied with the width of the machine. The whole of the bulky and heavy side portions of the frame had in such working to be treated as a single work piece.

It is the primary aim and object of the invention to obviate this drawback, and all projecting parts, recesses and the like have been removed from the frame, and the upper surface has been made entirely plane or straight from side to side and the machine parts have been provided with flat bases.

As an equally important object the invention contemplates the provision of a machine frame designed so that the various machine parts may be mounted thereon irrespective of any given succession in mounting the parts. According to various requirements, the said parts may thus be disposed in varying succession on different machines, or, one or more of the machine parts may be exeluded. In other words, it is not as hitherto, necessary to alter the frame pattern in each case where a departure is desired in regard to the succession of mounting the machine parts and with respect to the position of such machine parts.

An additional object of the invention contemplates the provision of a machine frame of such a nature that on any part or section of the machine having been worn out, such part may be easily replaced by a new part which may be ready made for substitution, without it being necessary for the machine to stand idle during a longer time than is required to remove the worn part from the smooth frame and to substitute the new part.

For instance, if the machine is injured by fire so that the movable machine parts and their flat bases or hearing attachn'ients are irreparably injured, this does not render necessary the discarding of the whole maof the chine, as has hitherto been the case, but the frame, which is generally left uninjured by the fire by reason of the solid structure thereof, may still be used to receive thereon the new machine parts.

e The arrangement is disclosed in the accompanying drawings. Fig. 1 shows a plan view of a planing machine in accordance with the invention, and Fig. 2 is an elevation thereof. Fig. 8, likewise, shows the machine viewed from the side, this machine having the same frame as in Fig. 2, but being arranged in a dlfferent way with respect to the mounting of the various parts of the machine. Fig. 4 illustrates a further modification with the use of a shorter frame, which latter, however, is unaltered as regards the shape and other details thereof.

Referring now, more particularly, to the drawing there is provided a machine of the general type of a planer comprising a frame or base 1 having a plane machine part supporting surface which extends from side to side so that various machine parts having flat bases may be arranged at different positions both as regards the length and width of the said surface and held in place thereon by means of screws 1.

. According to Figs. 1 and 2, there are, for instance, mounted on the plane surface of the frame 1, counted from the right hand side in the drawing, a first feeder device 2, a bottom knife 3, a cutter box 4, a second feeder device 5, a top knife 6, two side knives 7 and a stavecutter8. All of these machine parts may be accurately worked per se, independently of the frame, and they may be kept ready for quick mounting on the frame in place of parts that may have been worn out.

According to Fig. 3,the mounting of the various machine parts is altered for a particular purpose in so far as the cutter box 4: has been replaced by a first top knife 9, while the second top knife 6 and the side knife 7 are reversed.

According to Fig. 4, the cutter box 4 and the second feeder device 5 have been entirely excluded for still another purpose.

Evidently, the arrangement according to the invention not only facilitates an arbitrary mounting and exchange of the various parts of the machine, but also renders possible the workingof the said parts each per se, independently of the frame which in each particular case is-made according to a standard re therecn in varieus posi ticns as regards length 10 quire'meht: and Width cdmbinatidn with such machine What We claim as new and desire to SGGIH-G parts having corresponding flat bases suitby Lettere Patent of the United States of ableior arious pesitions; i V
